To recieve credit a writer has to show that they originated a certain percentage of a script. I assume that's why Eradicator became K and the Thanagarian Snarebeast is now a Plutonian Gnawbeast or whatever. It's the reason why twenty dudes can work on a script but in the end two guys get story credit and some lady you never heard of gets screenplay credit.

Oh right cool, didn't know that
